Swing Style

You'll often hear musicians talk about “swing style” when
playing jazz-style music. Confused? Relax, it's not all that
complicated.

A simple concept to grab off top is that when you have 2 eight
notes on a beat you play them is a long-short style. Ummm, is this
like having a dotted-eight note followed by a sixteenth note. Not
quite!

In the above example the dotted eight notes have a duration which
is three times that of a sixteenth.

Instead we want something which is more like this:

Playing gets a bit trickier when we have rests (doesn't it
always!). Remember that the eight note pairs have to be on a beat.
Again, the always present examples:

Sometimes, especially in older scores, you'll see both
dotted eighth-sixteenth and eighth-eighth pairs of notes. Unless there are
specific instructions,
it's very hard to figure what the intention of
the composer was, but there are several choices:

Play them exactly as indicated,

Play the eighth notes straight and the
eighth-sixteenths as swing notes,

Play both the eighth-eighth and the
eighth-sixteenths the same, as swing notes.

None of the above choices would be wrong. But, in a band you better
ask the conductor or leader ... it'll sound very odd (to say the least) if you
don't all play them the same way.

Notice that in the examples, above, it states “sounds pretty much like”. It's not an exact science. Swing style if very much
more a “feel”.

Another way to notate a swing feel is to use 12/8 time. You'll
often see this used in “doo-wop” and other, older, rock music.

Important: Even though the keysignature is 12/8 we still count
and conduct as if it were 4/4 time.

Finally, you may see a notation like this on some scores:

All this is doing is showing the eight note to triplet convention in a
graphical manner instead of “swing” or “swing style”.
Again, if in doubt, ask.
